This calor style taper set is made with 304 Stainless Steel.  These tapers can be autoclaved and reused.  Each taper is 2″ in length and tapers down 2 gauges smaller than the listed size. For example, a 0g (8mm) taper at its thinnest point is approximately 4g (5mm).  Calor Style Tapers are thicker and recessed so you can fit the jewelry inside the taper; this helps prevent slipping while stretching.  The chart below shows the thickness and diameter of the taper.
